I put my PGWP and and flight ticket from when I last came in to Canada.For me the biggest worry is the "Proof of entry and current status". I just provided my PGWP because the guide said provide your most recent work permit. Not sure what's gonna happen.
Also i didn't have a medical and PCC so I submitted a lot of evidence of my applications for both, so I hope they accept it. Other than that, I think I was mostly fine.
